What is calorie (IT)?

Calorie (IT) is a historical energy unit representing the heat required to raise 1 gram of water by 1 °C, used mainly in classical thermodynamics and steam-engine calculations.

What is a therm used for?

A therm is a non-SI energy unit primarily used to measure natural gas quantities and specify energy content in utilities and industrial heating.

Why convert calorie (IT) to therm?

Converting calorie (IT) to therm helps translate older thermodynamic data into practical energy units for natural gas consumption and modern energy analysis.
